btw i've seen multiple threads saying that going BotRK over Stormrazor is better and after testing it, the dps was far superior (the way i calculated dps was standing still aa the dummy until it has 100 hp, then aa until the numbers stabilized for BotRK and stand sill aa the dummy until the numbers stabilized for Stormrazor to negate the first aa with crit). my build was BotRK/Stormrazor with RG and Greaves.

BOTRK will almost allways (at least initially) do more damage to dummies than any other AD item because those dummies have a lot of HP, you should test it against champions to make a more accurate comparison.

I determine DPS values through calculations using the formulas on the League wiki, not by experimentation. In that sense, they're "perfect" DPS values, and slightly higher than what you might be able to pull off in an actual game, which is why I also include average damage per basic attack in the spreadsheet.

As someone else has pointed out: practice dummies have 10k health and only 100 armour, so BotRK's on-hit is going to average out to about 196 post-mitigation damage per auto, whereas if you take the tank stats I use for my calculations (4315 health, 258 armour), the average is around 47 post-mitigation damage.

BotRK is still good, especially in combination with Rageblade, but it's more of a situational item.

The thing about runes is you can't really compare them, because their effects are too varied; there's a reason most people say they're up to preference. You can always check post-game stats to help you make a decision, but, for example, Press the Attack and Fleet Footwork have completely different purposes, and you're much more likely to want to change between them depending on your lane matchup, or team comps, as opposed to sticking with one because of your build.

Personally, I prefer Press the Attack over Footwork, but I can't guarantee you'll feel the same way, and I'd still take Footwork if I anticipate a rough matchup.
